Historic plumbing retrofit. ARB-approved.
We upgrade cast-iron stacks, install modern pressure lines, and navigate Board of Architectural Review approval without compromising 200 years of Charleston character.
What we do
Cast-Iron Stack Replacement
Diagnose deteriorating cast-iron stacks, plan replacement routes that minimize wall damage, and coordinate with architects on interior finishes. We handle lead-based paint protocols and disposal.
Water Service Upgrade
Remove lead service lines and upgrade to modern materials—copper, PEX, or PVC—using concealed routing that respects historic walls. We guide you through EPA compliance and local permit requirements.
ARB Navigation
Design Review Board approval for plumbing modifications in historic districts. We prepare submittals, coordinate with preservation specialists, and ensure your retrofit meets Charleston design standards.
Why Dock & Stack
Preservation expertise
We work with architects, conservators, and the Board of Architectural Review. Every retrofit respects the original fabric while meeting 2026 code and safety standards.
Coastal resilience
Charleston's salt air and humidity demand material knowledge. We spec corrosion-resistant solutions and design drainage for humidity-prone masonry walls.
Transparent process
Before we start, you'll have a written scope, timeline, estimate, and our assessment of what ARB approval requires. No surprises when the walls come open.
Local anchoring
We live and work in Charleston's Historic District. We know the builders, architects, and the DRB staff by name. We're here for the long term.
